No transfer record matches. ARIN's statistics show it available on 2014-03-20 and allocated (dated 2014-03-21) on 2014-03-22. The tracker saw this range released from hold on 2014-03-17 (192.196.208.0-192.196.223.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics now list it as 'available'; reissue not confirmed

ARIN's statistics show it reserved on 2014-03-16 and available on 2014-03-18. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2013-12-13, 94 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2014-02-11. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2013-05-29) on 2013-12-12 and reserved on 2013-12-14. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2014-02-11. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2013-05-28 and allocated (dated 2013-05-29) on 2013-05-30. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
